Initial start-up is the most critical time in the life of any camshaft. COMP Cams® has taken great pains to develop what we feel is the best protective break-in lubricant on the market. It must be spread generously on all lobes of the cam, on the bottoms of the lifters, and on the distributor gear when installing a cam. This is the instant protection you need to guard against any premature wear.

Comes in a 4 oz bottle.
